Garbage Collection with LLVM

  The Memory Pool System (by Ravenbrook)

  

  I am trying to implement garbage collection for my language because I want memory management for arrays/lists and strings. I am looking through LLVM's garbage collection page but the documentation isn't great. Are there any other resources that offer more concrete steps to implement garbage collection? Would it be wise to circumvent LLVM all together for garbage collection and only use something like the Memory Pool System? Thanks!

  IME the MPS is hard to set up correctly, and I've heard in Clasp they got in performance trouble, as per-thread allocation buffers were too small and they couldn't make the buffers larger. But indeed being conservative on the stack is a fine choice; someone mentioned Boehm being easy to use, and the MMTk is a newer option which allows for bump-allocation and being precise on the heap (like MPS), but at the moment you have to provide your own stack scanning code.
